Brightening film (BEF) has a wide range of applications. Daoming Optical is a leading company in my country.

Brightening film (BEF), also known as condensing film and prism film, refers to a layer of optical film with a uniform prism pattern produced by precision molding using acrylic resin on the surface of very transparent PET. The light-enhancing film has the characteristics of enhancing light and improving brightness, and is widely used in mobile phones, cameras, computers, LCD monitors, car navigation systems and other fields. There are many types of light-enhancing films, including multi-functional light-enhancing films, micro-lens light-enhancing films, micro-prism light-enhancing films and reflective polarizing light-enhancing films.

The main raw materials of the light-enhancing film are acrylic resin and polyethylene terephthalate (PET). Acrylic resin has the characteristics of easy processing, anti-aging, light resistance, and good color retention, and is widely used. In 2022, my country’s acrylic resin output will reach 1.734 million tons, a year-on-year increase of 7.2%. Although my country’s acrylic resin production continues to increase, it is still unable to meet the production demand for light-enhancing films. Products are highly dependent on imports, which brings certain challenges to the development of the light-enhancing film industry.

According to the “2023-2028 China Brightening Film (BEF) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center Display, light-enhancing film has a wide range of applications, including mobile phones, cameras, computers, LCD monitors, car navigation systems, etc. LCD is the largest demand side for light-enhancing films, accounting for approximately 70% of the demand. With continuous breakthroughs in production technology, my country’s LCDs are gradually developing in the direction of large size and lightweight, which will bring broad market prospects for light-enhancing films.

The world’s leading companies in the field of light-enhancing films include 3M Company of the United States, LG Company of South Korea, Jiawei Optoelectronics Company of Taiwan, etc. 3M Company of the United States was the first manufacturer in the world to develop light-enhancing films and has now become the world’s largest supplier of light-enhancing films. The main manufacturers of light-enhancing films in my country include Daoming Optical Co., Ltd., Changzhou Huawei New Materials Co., Ltd., Ningbo Jizhi Technology Co., Ltd., Ningbo Dongxucheng New Materials Technology Co., Ltd., Shenzhen Xinfuyou Electronic Technology Co., Ltd., Xinsen ( Shanghai) Functional Film Industry Co., Ltd., etc.

Daoming Optics is my country’s leading light-enhancing film company and occupies a dominant position in the market. In recent years, Daoming Optics has focused on the R&D, production and manufacturing of optical film products such as light-enhancing films and quantum dot films. With in-depth research and development and technological advancement, the output and quality of TD Optical’s light-enhancing film have been continuously improved. According to Daoming Optical’s annual report, the company achieved revenue of 1.28 billion yuan in 2021, a year-on-year increase of 1.4%.

Industry analysts said that as an important optical film, light-enhancing film is widely used in the LCD field. With the rapid development of downstream industries, my country’s light-enhancing film The scale of the membrane market will further expand. There are many light-enhancing film manufacturers in my country, and the market competition is relatively fierce. As a leading company in my country, TD Optics has continuously improved its product quality. It is expected that in the future, with the continuous advancement of production technology, the application scope of light-enhancing films in my country will be further expanded.
